  1. B assembled the rear suspension on the Impreza. To make the Mustang rear calipers fit the Subaru front rotors I turned the rotors a little thinner, about a millimeter total. Second side I had to run a lot slower than the first. Since the opposite side of the rotor wasn't up against the jaws it was chattering at anything above about 100rpm. Also we only had one banjo bolt so I made another one. Will probably eventually get legit banjo bolts and better caliper mounting bolts but they all work well enough for now. Rear suspension and brakes assembled. ABS sensors and parking brake cables just zip tied up for now. Will eventually remove ABS cables and make brackets to connect parking brake cables. Black stuff running down exhaust is carbon washed out of the engine by excessively rich mixture when we first got the engine running. I cleaned up the wiring in the engine compartment, still some work to do there. Ditto the interior. Ready for the first test drive, just have to lower the car. Been on jackstands for way too long. For some reason the cam signal issue is back. Engine still runs but not as smooth as it has been, so I probably need to call Haltech again. On the plus side we drove the car around the block and everything important seems to work. All three pedals, shifter, and steering seem to do what they should. Didn't notice any tire rubbing or bad noises or vibrations. Didn't leak a drop either.
  2. Thanks. "Patiently executed" mainly because B and I had a ton of other work going on last year. Have had mixed results with Haltech tech support but talked to a guy a few days ago who remoted in for about an hour and got me mostly sorted out. The downside is I'm not sure exactly what we were doing wrong. He messed with the cam settings but I'm pretty sure wound up with something I've tried before and mostly what I thought they should be. Also not sure on the fuelling, he did disable some things that might have been throwing it off and reloaded the base fuel map from their EZ30 file and just changed the injector cc. The upside is I now have a file that seems to work well. While he was adjusting things the coolant temperature was slowly creeping up, eventually over 200F, but the fans weren't running. I hadn't set up one of them, the other one had blown the 20A fuse. I replaced the fan fuses with 30A and when we were running it the next day with both fans running the temp stabilized at about 206F. That seemed high to me but after it cooled off it turns out it was about a quart low on coolant (we hadn't connected and filled the overflow). Seems to me my 2002 (OB EZ30) was doing that when I first got it and it had a minor head gasket leak, if you revved it up at all the coolant temps would drop, I assume because the temp sensor would be in an air pocket at idle. I then rewired the cam position sensors I'd disconnected. All four of them read and we have gotten them to change but often they are just at zero when we think they should be something else so I need to research that more. B made this bracket for the Haltech, fusebox, and wideband module almost a month ago. Painted that and bolted it in. This positions the Haltech and fuse box in the opening for the passenger side airbag in the dash which should make connecting to it and checking fuses fairly convenient. Also the Haltech is supposed to be water proof but I really don't want to submerge it. I don't think the wires for the wideband will be long enough to reach up there so it will probably have to go somewhere else. Don't think I posted a picture of this, fuel line wiring under the cover. We made and painted and installed brackets for the coolant and PS reservoirs. B made this bracket for the gas pedal a while back, I recently bolted it in place properly. I turned some washers for the rear lateral links since they will be adjusted tie rod style, more stable and reliable than the eccentric method. Still waiting on a few parts for the dealer but we could probably get the car driving in a day at this point.
  3. B got a small CNC mill a while back. He's gotten it running and thought a good project for it would be spacers for the bumper so we don't crush the "frame rails" when we bolt it into the body. Rear brumper painted and installed. He's got a new (to the car) hatch and lights he's been waiting to put on so he'll probably do that soon.
  4. I swapped the stock fuel pump out for this Deatschwerks pump a few weeks ago. Will keep stock one as a spare. Z wired some plugs on my light bars that plug into the stock fog light plugs. Engine compartment is getting close. Have to mount the PS reservoir and clean up wiring. Got the cam sensors to show up on the Haltech but the engine won't run with any of them connected to the main cam signal, waiting to hear back from them on ideas there. Also have to have super low values in the VE table to run close to 15:1 at idle but we have gotten it to do that now and it runs pretty smooth and smoke free. Got the parts back from paint. B installed bushings in the various rear suspension components. Used Whiteline mainly for ease of assembly. Ordered some R180 inner CV dust shields and another wheel bearing, then should be able to assemble all that. Fuel tank guards installed. Transmission crossmember/skid went in much more easily than we expected. Usually after removing these things and welding them off the car there is some amount of bending and hole slotting required. Middle portion of exhaust not fully installed, might have to come back out to install stock shifter. Waiting on bushings and roll pin for that. Front skid installed. A little bending and slotting was required to get that to bolt up to the bumper but not too much. Front bumper and lights installed. Car is getting really close to driving but there will still be a lot of things to do.
  5. Still getting crank trigger errors on the Haltech. Oscilloscope trace looks good to me but that doesn't mean much. Have mostly been running the engine on an old EZ36 base map one of the guys from Haltech imported into NSP for me. Engine starts and idles readily. It's giving me DTC codes P0373 and P1302. Also while running, under "trig errs" it says "home tooth count error". Showing exhaust and intake cam angles not calibrated while running. It also did this when we ran it on the EZ30 base map. Tried switching the wires to the crank sensor and then it wouldn't run at all, switched them back. Also with both maps it was running super rich. So much unburned fuel it was dripping out joints in the exhaust system. Tried leaning it out and eventually got down to about 0.2 for the entire base map (started at about 12 at idle). Just a couple percent injector duty cycle while running. Dropping that down to 0.1 the engine wouldn't start IIRC. I can make the map display more decimal places but can't seem to adjust it in finer increments than 0.1. Wideband never read over about 11 or 12:1 for most of this. Eventually changed the injectors (in the software) to some larger ones, anywhere from 750 to 1400cc/min seemed to improve things with 750cc probably the best. At this point the idle is smoother and wideband is reading 12-17:1, sometimes one bank considerably leaner than the other. I had assumed due to some crank position sensor issue it's just not burning most of the gas it's spraying in but now I'm not sure. Fuel pressure regulator set at 40psi, as indicated by sensor and a mechanical gauge a while back. Noticed on the trigger page it was set to 58 teeth (but can't be changed). I switched to the EZ36 trigger setup and it changed to 36 teeth but seemed to make no difference. Tried wasted spark as I've read that can be a good diagnostic test on this kind of problem and if anything it ran worse. Also tried reversing the inputs and outputs for the cams between banks 1 and 2 (in the software) and it didn't seem to run any different. Can't get any readings off any of the cam sensors on the oscilloscope so far. If anyone has any ideas I'm all ears.
  6. B and Z and I worked on the Impreza Sunday. No pictures at the moment but we made some good progress. Ran the engine more but it seemed to be running rougher than before. We were getting an error message about the crank trigger. Tried reversing the wires on that and then it wouldn't run at all. Tried a few base maps, they all ran rough. We were getting a lot of unburned fuel in the exhaust. On the plus side I fixed the fuel leaks by replacing some injector o rings. The fuel pressure, air temp, and coolant temp sensors all seem to read accurately on the Haltech now. Wideband and MAP sensor seems to be working. Tach on the Haltech and gauge cluster work, alternator is now charging. Still not sure exactly how we're going to wire the AC. The compressor on the EZ36 seems to be some kind of solenoid controlled variable displacement job normally controlled by monitoring both refrigerant flow and pressure but the one from the EZ30 does look like it will bolt in place. Pretty low priority at this point but it'd be good to do as much wiring as we can up front. Will post more pictures and details later.
  7. B and I made more progress on the Impreza too. Got the headers welded. Seems like getting them ceramic coated would cost $350+ so I'm just going to skip that. They are stainless and as B pointed out, they'll probably fail due to mechanical damage rather than corrosion. Did some welding on other portions of the exhaust. Should have tacked more things together before removing all the tube work underneath the car. Sprayed the welds with a little high temp paint, most of it is already aluminized. While we were at C's shop he gave me a radiator and fans that had the right plugs I need so I spliced those in to my fans. Note the polarity is reversed since we're using them as pushers. Will put more detail on that in the swap thread. Painted the mounts and bolted the fans in. Spliced wires from Haltech to where they went to stock ECU to switch on the relays. Siliconed a grommet for an air temp sensor in the air box. Definitely not pretty but wanted to get something in place. Wired in the connector. Made a couple of tabs, welded them on the bumper and painted them. Drilled a couple holes in the bumper beam. The Outbacks have hoods on them so the light only shines down but they have a different wire connector. The Impreza lights don't have hoods so I painted all but the bottom of them. Need to fab a rear bumper for this thing sometime but this seemed like the simplest and cleanest solution for now. Open to suggestion on how to do this when I fab a rear bumper. Planning on 2x4" steel tube like the front sticking out at least a few inches beyond the hatch. On my old Impreza I just screwed the plate and some aftermarket license plate light to the hatch but I'm not keen on doing that to this car.
  8. Mostly unrelated but B and I stopped by C's shop. Standard EJ25 with a rod sticking out. Has another one with rod knock, in his dreams he will eventually make one good engine out of two. The main reason we were there was to remove and disassemble a CVT out of a 2014 Outback. C bought the car pretty cheap knowing the transmission was bad and since he's cheap he wants to try to fix the trans rather than just replacing it. It still ran and drove but made horrible noises. Car has 208k miles on it but has minimal rust. Previous owner supposedly pulled his 18' pontoon boat in and out of the water with it regularly, which may not have been a good idea. Once we removed all the bellhousing bolts, the transmission wasn't too hard to remove. We first tried unbolting the front/bellhousing from the trans but that didn't seem to work. Then we unbolted the top cover and removed this valve body which also didn't accomplish much. Figured it was a long shot but removed this front cover and oil pump, also no real progress. These screws are pretty crazy though. Took the tailhousing off, standard Subaru auto trans clutch pack for the rear drive. Didn't really look at it at the time but seems feasible that some kind of planetary low range might be possible. Took the pan and filter off and some kind of splash/windage tray. Then we were able to split the case. Transmission is pretty simple really. Sheaves still look very smooth. Some burs/wear on the top edge of the pulley on the left, I'm guessing that's what was causing the intermittent nails on the chalkboard noise C told us about. Pretty sure we found the root of the problem. This used to be spherical. C plans on replacing that bearing, a sensor we broke during disassembly, and putting it back in the car.
  9. B and I finished the remaining fab and paint on the skidplates and bumpers. Round tube bumper is for the rear of B's Forester, everything else is for my Impreza. Dropped it all off at paint today. Didn't listen to slammo and travelvw and asked the paint shop to match the gold color on the bottom part of the body for the front bumper and skidplate. Everything else will be black.
  10. Most of the wiring and modules we removed. Keyless entry, airbags, TCU, ECU, aftermarket cruise wiring. At first we couldn't remove the ignition key from the lock cylinder even in the off position. If you plug the shifter (big white thing) in to that white wire plug and have it in park, then you can remove the key. Those blue and red wires go the park position sensor. The two black wires below that go to the lock cylinder seem to be the culprit. If you unplug them at this connector under the steering column you can take the key out normally. Then you don't have to deal with the park position sensor. The black connector with two white wires is the other side of the connector. Alternator wiring. The two big white wires go to the large post. Then the black/white wire is the same on both cars so I spliced those. Spliced the other one. I did order a wire plug for this so I can get rid of the splices. Spliced a wire off the coolant temp sensor to the dash but that caused the Haltech to read low. Just have temp sensor wired to Haltech for now, will probably have to use an output from the Haltech to drive the stock temp gauge. Here we have the wires for the instrument cluster. connector a/i10 pin 8 R/W check engine light (from Haltech) pin 9 G/W oil pressure switch (from engine) pin 10 G tachometer (from Haltech) connector c/i11 pin 11 W/G coolant temperature (need to figure this out, see above)
  11. B finished welding the rear brumper yesterday. We also finally got the EZ36 running in the Impreza. Seemed to be running on all six, the only leak we noticed was one of the injectors so I should get new o rings for those. Cranked it for a while to get some oil circulation and maybe pressure. Even without the fuel pump running it started to fire when we plugged in the ECU. Fired right up with some fuel pressure, responds to throttle pedal. Only ran it for 5-10 seconds a few times. Still needs a lot of little things but a bit of a relief to hear it run. I'm going to try to put all the details of the engine swap on this thread: Will probably start copying some of the relevant info from this thread into there and use this thread for our usual fabrication, repairs, and trip reports. Thought it might be handy for future reference to have all the engine swap info in one place.
  12. Download the FSM from jdmfsm.info, most of the following is from that. Pinned out connector to EZ36 Some Impreza specific wiring: Was looking for a good source of 12VDC with the ignition on that's not shared by any other fuses. Since we removed the airbags, computer, and wiring, it was convenient to tap into the airbag harness connector near the dead pedal. Ran the pink wire from pin 13 of the Haltech to that. Pin 6 connector B31 red wire as seen below: Almost spliced into the B/R wire running to the fuel pump by the passenger footwell but decided to tap into the connector that normally goes to the fuel pump relay (white thing on the left side of the picture). Ran the orange/blue wire from the Haltech fuse box there. Pin 4 of B46 black/red wire as shown below: Also wanted a dedicated but fused battery voltage source so tapped into the ABS connector since that will no longer be functional. Goes through the main 80A fuse and a 50A fuse in the main fuse box and then over to the ABS module (W/R wire marked B). Plugged the red, red/white, and red/green wires for the Haltech fuse box in to that. Used a large ground wire there too (black wire marked G), ran the black ground wire from pins 10 and 11 of the Haltech to that. Pins 23 (black) and 25 (white/red) of F49 as seen below: Simplest way I could figure to do the starter circuit was to splice these two wires (large W/R and W/B) that originally went to the shifter on the auto trans. Cut them on the large side of the factory splices and spliced them together. Large white/red and white/black wires of B12 as shown below: For some reason we had to unplug the stock ECU for this all to work properly but we were obviously going to do that regardless. I plan on adding more detail to the above and other wiring as I have time.
  13. As noted above this is for an STI accelerator pedal, I think the pinouts on the Legacy/Outback and possibly the one shown on the Haltech site are different so definitely verify that. Most of that was figured out from the basemap I got, Haltech's site and instructions (their color coded wiring diagrams are great) and the FSMs. One minor hurdle we had was the Haltech EZ30 basemap being set up for a PWM pump (I think), had to switch that to the B/Y wire so it would actually turn on the fuel pump. Fuel pump seems to run continuously with ignition on even if the engine isn't running, haven't looked to see if or how that can be changed yet. Also had to adjust the pot position on the accelerator pedal to keep from getting an error at full throttle. Simple, just two phillips screws. Also have to calibrate the accelerator pedal and DBW throttle, also simple, just follow prompts on the screen.
